I'll tell you all what I run...
Up front: KYB Buzz Spec struts, GC coilovers (450lbs/in), SPL tension rods, Tein inner/outer tie rods, Tein Camber plates, ebay strut tower bar, Suspension Technique sway bar, Nismo Power brace, and whiteline LCA bushings. My struts are set at full stiff on drift days. My camber is set to full negative (roughly -2.7 degrees), my toe is 0, and my caster...hmph, I forgot. Currently I'm running AVS ES100's 215/45/17 mounted on 17x8" 5zigen FN01RC's at 36psi (cold).
Out back: KYB Buzz Spec struts, GC coilovers (350lbs/in), SPL RUCAs, SPL Traction rods, Hicas lock bar, SPL aluminum subframe spacers, Suspension Technique sway bar, ebay strut tower bar, whiteline RLCA bushings, and a S15 HLSD. On drift days the rear struts are set 1/2-way. I take whatever I can get in tires, but at the last DDay I was running 215/45/17" Falken ST115's on my 17x8" G35 wheels w/ around 38psi (cold). Alignment in the rear is -1.25 degrees of camber, as close to a 0 toe as I could get (I think it's about a .15 degree or less toe in).
I'm always trying new things with different results though...I'd say just experiment and figure out what you like best. And no, my car is not an oversteer machine...I try to make it handle as neutral as possible.
